TextFrame.SlideNumberPosition contains only index of the first appearance of the slide number.
What if TextFrame has two or more “slide number” or similar objects inserted?
One text frame can have only one slide number. On practice, it’s always “*” character.
Other objects like date/time, header, footer have other properties.
PowerPoint allows to insert two and more slide numbers per TextFrame. So if we insert it twice we get “**” text but there is no way to determine if both “*” characters are slide numbers.
Is it possible to support IEnumerable interface for
TextFrame.SlideNumberPosition?
This position stored in special record and there is place for only one number.
We will investigate how PowerPoint store several values and most probably
Aspose.Slides will support it soon.
